  1. 01-LP-UPS : ULTIMATE TAKEDOWN PIN SET

    UPS-S™  Ultimate Takedown Pin Set.

    Precision machined on Swiss style turning centers our Ultimate Takedown Pin sets are manufactured from the highest quality materials to the highest standards.
    They ship complete with our 3D printed rear pin removal tool (RTT™).
    The Patent Pending UPS™ (Ultimate Pin Set) allows the user to install and remove an AR15 Pivot Pin without the use of a tool.
    The unique design incorporates a ramped groove that holds the detent in place at the time of installation and another ramp allows access to the retaining slot
    at 90° to groove.
    Pins feature Patent Pending aggressively crenulated heads for improved grip, this facilitates easier removal of the pin from the receiver.
    The rear pin features the same retaining slot and ramp, meaning that it can be removed easily by sliding it to a halfway position and then rotating.
    This causes the takedown detent to ride up the ramp and onto the outer surface of the pin, making remove extremely simple.
    QUICKSAFE™
    Our UPS™ Pin system has a built in safety feature that can be utilized by anyone wanting to make it difficult for an Upper Receiver to be fitted to a Lower Receiver.
    To render a lower receiver inoperable the user can quickly remove the front Pivot Pin (Spring & Detent) and insert it through the rear Takedown pin hole from
    the other side of the receiver. Then remove the rear Takedown and allow the Pivot Pin to retain its detent.
    If the pin is rotated so that the detent registers with the groove on its end then it becomes impossible to remove the pin without removing the castle nut and end plate. 
    It is now impossible to mount an upper receiver group to the lower and have a functioning assembly.
    Pins are manufactured from 17-4PH stainless steel in H900 condition and then QPQ Nitride finished.

  3. 01-UP-UFA-S : ULTIMATE FORWARD ASSIST

    LANTAC UFA-S, Ultimate Forward Assist (Solid)
    SKU: 01-UP-UFA-S

    Lantac UFA-S
    Ultimate Forward Assist (Solid).
    The UFA-S is precision swiss lathe turned & manufactured from certified 4140 Cr-Mo steel, giving improvements to strength, corrosion resistance and durability over the original materials.
    Parts are all heat treated to 48-52 Rc (Rockwell C).
    In addition all parts are QPQ (Quench Polish Quench) Nitrided for improved corrosion resistance and enhanced lifespan.
    The main Plunger spring is manufactured with the improvement of Stainless 316 music wire (as per ASTM A313) for enhanced corrosion resistance.
    Closed end coils are also used rather than the original open ends for improved seating and alignment. Springs are stress relieved and air cooled.
    The Plunger Detent Spring is improved and manufactured from Zinc plated music wire (as per ASTM A288) for enhanced corrosion resistance.
    Springs are all stress relieved as per the mil specification. 
    The assembly is retained within the upper receiver with an improved spiral design pin as opposed to a slotted version for increased strength and durability. Pins are fully certified by the manufacturer.
    The design of the Cap has been improved by reducing its diameter and snagging potential, creating a more streamline surface flow when assembled into the upper receiver.
    Exterior surface knurling around the caps edge allows for positive engagement with a gloved or naked hand while removing the circular ridge that exists on the current design.
    Weight of the assembly has also been improved to 20.227g (.7135oz) from 22.481g (.7930oz).
    All outer details are bead blasted to create a satin, reduced reflectivity surface prior to finishing.
    Manufactured in the USA from USA sourced materials and finishes.

  12. 08-153 : Maritime Bolt Catch
    Geissele® Automatics
    08-153 : Maritime Bolt Catch

    The Geissele Maritime Bolt Catch is designed with the warfighter in mind and will work with any lower receiver designed to accept a mil-spec M16/M4 Carbine bolt catch. The increased surface area promotes ease of function when locking back the bolt or releasing the bolt after a magazine change. In addition, the extended controls add an increased functionality for left handed shooters who no longer have to break their grip to manipulate the bolt catch. Left handed shooters can easily reach the controls using the index finger of their left hand making magazine changes and locking the bolt back much more fast and efficient. Aggressive checkering covers the surface of the levers giving the Geissele Maritime Bolt Catch a textured surface that enables positive feedback to the shooters hand when being used with gloves or at night. Manufactured from properly heat treated 8620 steel and manganese phosphate coated, the Geissele Maritime Bolt Catch is intended to serve as an enhanced mil-spec replacement and assist in giving our warfighters overmatch capability with the M16/M4 carbine platform.

    Please Note: A mil-spec bolt catch spring and plunger are required for assembly and are NOT included. If the Maritime Bolt Catch is replacing an existing mil-spec bolt catch, please use care when disassembling the component from your lower receiver as you will need these parts to install the Maritime Bolt Catch.
    Compatibility with billet AR-15 lower receivers is unknown. Please also note that the extended controls of the Geissele Maritime Bolt Catch will partially cover the pin hole for the hammer, a smaller punch may be required to push the hammer pin out of the receiver from the left side, and the hammer pin should only be installed from the right side of the receiver
